It uses a scoring system based on specific criteria to identify potential spam messages. Users are empowered to filter and control unwanted content.

How Does SpamAssassin Work?

1. Scoring System: SpamAssassin analyzes email headers and content, assigning a score to each email based on certain criteria. This could include factors such as specific keywords, poorly written headers, or email addresses from certain senders.

2. Score Threshold: Users can set a predefined score threshold. If an email surpasses this threshold, SpamAssassin marks it as potential spam.
